Recently the Plants vs. Zombies Plush Wiki has had an influx of vandalizers. Sometimes they rename, or move, pages to random garbage like "firepam" or "Harry goes to taco bell." I want to make it so normal users cannot rename/move pages, but I cannot figure out how to do so.
Go to the dropdown underneath the 'edit' button on each particular page (as far as I'm aware, there's no way to do this to the whole wiki) and click on the 'protect' button. There should be a box underneath the first section which says 'unlcok further protect options' - check that and then change the 'move' section from 'allow all users' to 'Administrators and Content Moderators only'.
